摘要： The objective of this study was to evaluate a novel multi-blade Shear (MBS) method for measuring texture properties of both raw and cooked broiler fillets (pectoralis major) with the woody breast (WB) myopathy. A total of 180 broiler breast fillets (60 normal [NOR], 60 moderate WB [MOD], and 60 severe WB [SEV]) in two meat states (fresh never-frozen, n = 144; frozen/thawed, n = 36) were chosen based on their WB scores. In each trial, half of the fillets were used for measuring raw meat texture and the other half for cooked meat texture measurement. Blunt Meullenet-Owens Razor Sear (BMORS) was used for comparison. In fresh raw broiler fillets, both the MBS and BMORS methods detected differences between NOR, MOD, and SEV fillets (P < 0.001). In cooked broiler fillets, the methods were equivalent in their ability to separate SEV from NOR fillets. The MBS measurements showed greater Spearman correlation coefficients with the WB scores (r(s) >= 0.70 in raw and >= 0.33 in cooked) compared to the BMORS measurements (r(s) = 0.63 in raw and <= 0.27 in cooked) for both fresh and cooked breast fillets. In addition, the MBS measurements were either as precise as or more precise than BMORS measurements regardless of meat condition (fresh vs. cooked) and the shear parameter. These results suggest that the MBS method is more reliable in measuring tactile characteristics of broiler breast fillets with the WB myopathy compared with the BMORS method.
